|“Heh. Sounds pretty tough. But trust me, Nya is worse. Like, so much worse. Let me tell you. I was test driving my newly-built ultimate noodle truck of crime. When for no reason at all, that nosey do-gooder judgey Nya comes out of nowhere and starts messing with me.”|
|— The Mechanic to Ultra Violet and Fugi-Dove in "The Absolute Worst"|
The Mechanic is a former employee of Master Chen who was at one point imprisoned in Kryptarium Prison. During the Second Serpentine War, the Mechanic was affiliated with the Anacondrai Warriors, repairing noodle trucks for the underground crime organization. After Chen and his army were banished, the Mechanic went out of business with his employer having been cursed. Due to his involvement with Chen, he was locked up in Kryptarium Prison, where he earned the name "The Mechanic."
After the Battle of Stiix, the Ninja were imprisoned in Kryptarium after being framed for several crimes. Upon entering the prison, they were confronted by the inmates, including the Mechanic, who was vengeful after the Ninja defeated Chen and put him out of work. When the inmates started fighting the Ninja, the Mechanic went after Zane to steal some of his robotic parts but thanks to P.I.X.A.L. he was stopped from doing so. Following Jay's final wish, the Ninja were never sent to Kryptarium and the Mechanic didn't confront them.
At some point, the Mechanic escaped Kryptarium Prison, but was defeated by Kai and Zane and was subsequently placed back in prison.
However, the Mechanic managed to escaped Kryptarium Prison again and associated with a mysterious AI named Unagami.
Before Master Chen's banishment to the Cursed Realm, the Mechanic made money repairing the vehicles of the Anacondrai Warriors. After their defeat at the Corridor of Elders, he was arrested and sent to Kryptarium Prison where he swore revenge on the Ninja with the intent of tearing Zane apart for parts.
When the Ninja arrived at Kryptarium for being framed for a crime spree, the Mechanic opened his and several other inmates’ cell doors, leading them to confront the Ninja. Explaining his situation to Lloyd, he demanded they hand over Zane to use as spare parts in exchange for the grievances he believed the Ninja had caused. However, before he could take any action, Warden Noble arrived, ordering him and Lloyd to shake hands.
During the following meal in the cafeteria, the Mechanic confronted the Ninja again but was dismissed by them as at most a fourth-tier bad guy. Infuriated, he started a fight during which the Mechanic dragged Zane away, determined to take him apart. However, an electric shock orchestrated by P.I.X.A.L. sent the Mechanic flying back and he was returned to his cell by the guards before he was able to inflict any further damage to the Nindroid.
Due to Jay's final wish, the Mechanic never confronted the Ninja in Kryptarium, due to them never being sent there.
The Mechanic manages to somehow break out of Kryptarium Prison and fights Kai and Zane with a new arm that is similar to a flamethrower. However, Zane manages to freeze the villain in place, and then send him back to the Kryptarium.
The Mechanic was seen in the Kryptarium Prison several times, sharing one cell with a Sons of Garmadon member, watching the fight between Cole and Giant Stone Warrior, and later throwing random objects at Cole, for defeating and placing Giant Stone Warrior and Killow back into their cells.
While in the exercise yard, a newspaper comes at the Mechanic, who reads it, and discovers that the Ninja are gone before relaying the news to Ultra Violet, who tells him they breakout after lights out. Later that night after the guards turned off the lights, the Mechanic used his cybernetic arm to get the keys to his and Ultra Violet's cells before they escape through a tunnel she had dug in the prison. Once they reached the sewers, the Mechanic and Ultra Violet argue about who they thought was the worst (Zane or Nya) before Fugi-Dove shows up, telling them it is Jay. Once they heard Ultra Violet's story about her capture, the Mechanic tells her and Fugi-Dove about the time Nya stopped him and later stole his Noodle Truck of Crime before eventually listening to Fugi-Dove's story about his hatred for Jay, only to easily find it false, until they reach a grate, and start to make plans for crime breaking, only to end up captured by Samurai X when they had inadvertently triggered her hidden sensors, resulting in the three recaptured prisoners to proclaim her as the worst.
After stealing money from the Ninjago City Bank, the Mechanic went to his headquarters and told a computer about the Noodle Truck's upgrades. When the Mechanic asked if the computer can reveal his identity to him, the computer replied that he'll reveal his identity when the time is right.
After failing to use a noodle machine in his Noodle Truck, the Mechanic asks the computer if he was able to get a robot arm that is able to feel things. Luckily for the Mechanic, the computer was able to print blueprints of the arm, which the Mechanic quickly built. After testing out the robot arm, the Mechanic once again questions the computer's identity again, only for the computer to reply that his name is Unagami.
The Mechanic and his henchmen enter an old electronics warehouse and steal the Prime Empire Motherboard. However, they are spotted by the Ninja so he escapes in his Noodle Truck. After a short chase through the streets, he is captured and arrested when Cole ties him to a pole.
While the Ninja were investigating his hideout, Jay finds an old arcade cabinet which is titled Prime Empire. He inserts the recovered motherboard into the cabinet and a wave of red energy bursts from the machine. Before being escorted to the Ninjago City Police Station, he laughs wickedly as he hears the shockwave of red energy pass through.
The Mechanic was interrogated by the Ninja about the mysterious V-shaped symbol as well as Unagami, the latter surprising him. He then told them it was too late and it had already started. Lloyd then has the Commissioner take the Mechanic away while he gloats. As he was still gloating with officers dragging him, he peeks his head at the doorway to resume gloating before the Commissioner closes the door on his face.
Later, the Mechanic and the prisoners invaded Borg Tower to retrieve the original Arcade Pod. When they finally make it upstairs, the prisoners fight off the Ninja and the Mechanic tells Lloyd that Unagami plans to start a new revolution and that he'll be serving at his side. Moments later, Lloyd attempts to enter Prime Empire but was stopped by the Mechanic. However, the Mechanic was pushed by Zane, allowing the Ninja to enter Prime Empire while Zane escapes with P.I.X.A.L. and Cyrus Borg. When Soto tried to go after him, the Mechanic stops him, saying that they're only at Borg Tower to retrieve the original Arcade Pod. Although, when the Mechanic pressed the start button, the Arcade Pod wouldn't work, as Zane took the Prime Empire Motherboard when he escaped with P.I.X.A.L. and Cyrus.
The Mechanic and his henchmen ambush Zane and P.I.X.A.L. while they are investigating Buddy's Pizza. Zane is electrocuted by one of The Mechanic's gadgets. When P.I.X.A.L. checks to see if he's alright, but she too is electrocuted by The Mechanic.
The Mechanic explains to Zane that they are building the Manifestation Gate which requires Energy Cubes from the players who lost all of their lives. The Mechanic then demands the Prime Empire Motherboard, but Zane claims he destroyed it. Knowing that he's lying, The Mechanic unveils Wu who was captured earlier by henchmen. He goes as far as to threaten to harm Wu, so Zane finally confesses and gives him the motherboard. The Mechanic inserts the motherboard in the Manifestation Gate and also uses Zane for a power source despite having a high risk of being destroyed. A portal is created and The Mechanic waits for Unagami to enter.
Once the Manifestation Gate was complete, an anger-riddled Unagami escaped Prime Empire, along with his armies and the AI within the game. The Mechanic and his henchmen were overwhelmed by the spectacle and, ironically, ran away from the master they were serving. It is unknown if he was tracked down and rearrested following Unagami's surrender and redemption.
The Mechanic is sadistic, such as when he attempted to remove parts from Zane and used him to power up the Manifestation Gate.
He also has a bit of pride, as when he made up the story about how Nya stole his noodle truck.
At rare times, he was a coward, such as when he ran away after the Manifestation Gate started to go unstable.
